…or, Gun geekery alert!
Via Borepatch, we have Ballistics by the Inch, a fun look on the effect of barrel length on various loadings of pistol ammunition. I had to go straight to the .357 Magnum results. Why?
Well, at one point I had a Ruger SP101, a little snubby .357 revolver with the 2.25-inch barrel. And I can tell you that shooting full-house .357 out of that thing was quite literally a real pain. So I was thinking that for that kick I’d at least be getting a decent muzzle velocity, right? 1100-1200 feet per second? (The standard loading for a 125-grain .357 is 1450 fps out of a 4″ barrel.)
Yeah, not so much. Try about 1050 feet per second. It certainly beats a sharp stick, but I’d definitely be carrying something else given the choice. YMMV, and all that…
